When Should You Replace Your Boiler?

Knowing when to replace a boiler saves money, avoids cold winters, and keeps your home safe. Here are some of the key signs that a new boiler is overdue:

Boilers over 10-15 years old lose efficiency and fail more often
Rising bills with the same usage
Frequent repairs or one repair costing close to half a new boiler
Poor heating or weak hot water, cold spots or slow recovery
Leaks, corrosion, strange noises, or constant pressure loss
Yellow or flickering flame, which is a safety concern

If you’ve noticed any of the above, don’t delay - schedule a new boiler through GasWise today by calling us on 01295 597 961 for a no-obligation quote.

Choosing a Boiler Replacement: Your Options

Replacing a boiler should be simple and tailored to your home. Here are some of the main options we offer:

Combi Boilers

Compact and space-saving, combi boilers deliver hot water on demand without a separate cylinder or tank. They’re ideal for flats and small-to-medium homes where space is limited and you want instant hot water with a neat installation.

System Boilers

These work with a hot water cylinder to store ready-heated water, so several bathrooms can be used at once without pressure loss. They suit homes with one or more bathrooms and households that use hot water simultaneously.

Conventional Boilers

A reliable choice for larger or older properties that already have tanks and cylinders in place. They integrate easily with existing systems and provide steady hot water for busier households.

Fuel Choices - Gas, Oil, LPG

We’ll recommend the best fuel based on whether you’re on the mains gas network, off-grid (oil), or need LPG. Each option has different running costs and tank requirements, but we’ll explain each so you can choose the best for your needs.

Reviews:

Ruth Lewis

Fantastic work carried out on a tired shower room that was long over due a refit. Dan and the team were professional, friendly with excellent attention to detail nothing was too much trouble. We are thrilled with the final results!!!

Luke Taylor

We had our boiler serviced by gaswise for the last couple of years and the service has always been great. We had Jake come over this time and he went above and beyond by sorting out a loose tap that he noticed while servicing. It may seem like a small thing but goes to show how he goes above and beyond for his customers. Thanks for your help.

John Robinson

Very diligent company. Installation of two commercial boilers into a large church. Thorough site surveys carried out over three visits including specialist flue manufacturer and the boiler manufacturers. Well managed installation with excellent post installation hand over and follow up.

Alison Taylor

Jack initially came to service our boiler, he was friendly, professional and did a great job. We wanted our heating system flushed, so asked for a quote. This was sent the same day and our system was flushed through on the day we wanted, all ready for the winter months by Jack & Harry. Again a friendly professional manner, and our home left clean & tidy.

David Stemp

We just moved in to our new property on Friday, we reported the taps not working in the kitchen on Thursday, Ryan came around, identified the problem, and changed the taps. Great, professional service, Ryan was very friendly and professional. Thank you.

Jess Slater

Ryan completed a boiler replacement and a Landlords certificate for us on our rental property. He was friendly and efficient, and we really appreciate the effort he went to, to ensure we were happy with the installation and that we understood how to use it before he left. Thanks

FAQs

Can you remove and dispose of my old boiler?

Yes, we’ll safely remove and responsibly dispose of your old boiler. Disposal is usually included in the quote; we’ll confirm this before work begins.

How much does it cost to replace your boiler?

Prices vary by boiler type, fuel, and installation complexity - we’ll give a fixed written quote so you know the full cost upfront. Although replacing your boiler costs upfront, a modern system with smart controls and a system filter can cut your energy bills. In fact, the Energy Saving Trust estimates you could save up to £300 a year with a new boiler system!

Can you install smart controls or thermostats?

Yes, we regularly fit and configure smart thermostats, programmable controls, and zoning systems to improve comfort and save energy. If you’re unsure about any of this, please don’t hesitate to ask us any questions you may have.

Will a new boiler disrupt my home?

We always strive to keep disruption to a minimum. Our engineers protect floors, work tidily, and clear away at the end of each day. We’ll also explain any temporary loss of heating or hot water in advance, so there are no unwanted surprises along the way!

Is finance available?

If you’d prefer to spread the cost of a boiler replacement, please discuss this with us - we offer flexible repayment options through our finance partner, Novuna. We’ll explain terms and any eligibility requirements with you, so you’re clear on how this works.
